Last modified
CVE-2026-65593 is a medium-severity vulnerability rated 5.4/10 on the CVSS scale. n8n versions before 1.123.64, 2.29.8, and 2.30.1 contain a server-side request forgery vulnerability in the dynamic-node-parameters endpoints that lack authorization scopes. Authenticated attackers can supply absolute URLs in routing configuration to override baseURL restrictions and make the n8n server issue HTTP requests to arbitrary internal targets when SSRF protection is disabled.. EPSS estimates a 0.21% chance of exploitation in the next 30 days.
